FREDERICK WENTWORTH SAWYER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO OOOOON SPINNER COMPANY, A CORPORATION OF MAINE.

APPARATUS FOR SPINNING OR TWISTING.

SPECIFICATION forming part of Letters Patent No. 771,396, dated October 4, 1904.

Application filed February '7, 1902. Serial No. 92,989. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK WENTWORTH SAWYER, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Apparatus for Spinning or Twisting, of which the following description, in connection with the accompanying drawings, is a specification, like numerals on the drawings representing like parts.

This invention relates to an apparatus for spinning yarn or performing analogous spinning or twisting operations and winding said spun or twisted material on a bobbin or other suitable core or support in order that said material may be removed from the appliances concernedin its production in suitable form for subsequent operations to which it may be subjected or subsequent uses to which it may be put.

The invention consists partly in the combination of appliances which twist the material and collect the spun or twisted material in the form of a hollow coil with means for winding the said coiled material on a core or support such, for example, as aspool, bobbin, or coptube-when a suflicient quantity of spun or twisted material has been collected to properly fill a spool or cop or when the spun yarn has accumulated to the desired amount within the capacity of the spinning device, from which the spun yarn must be removed in order that the spinning operation may be continued or repeated.

The invention further consists in certain features of construction of the spinning appliances which contribute to their efiiciency, although not essentially involved in the novel construction and mode of operation of the spinning and winding appliances proper; and the invention also consists in the combination with the spinning and winding appliances of auxiliary appliances hereinafter described which contribute to the practical efficiency of the apparatus.

The active member of the spinning appliances proper consists of a hollow chamber adapted to be rotated at high speed, said chamber having an opening in its end-that is,

about its axis of rotationthrough which the material being spun enters.

For the purpose of illustration the material is herein shown as yarn spun from the usual roving, which is supplied to the hollow spinning-chamber by drawing-rolls of the usual construction, and said roving in passing to the interior of the rotating spinning-chamber is passed through a guide or eye, preferably located in the axis of rotation of the rotating chamber and having a traverse movement inside of the said chamber and in the direction of the axis of rotation thereof, said traverse movement serving to distribute the material as it is spun in the desired arrangement on the inner surface of the wall of the spinningchamber.

In referring to the operation of the appliances for spinning or twisting the material the term twist will be used as including either the operation of twisting together the fibers of a single strand, as in spinning yarn, or the twisting together of a number of strands, as in the manufacture of thread.

The mode of operation of the twisting and collecting or coiling appliances above described is as follows: The'end of the roving delivered from the drawing-rolls is passed through the guide-eye and is then brought into engagement with the rotating chamber. The engagement of the end of the roving with the rapidly-rotating chamber is sufiicient to cause the end of the roving and the portion extending laterally from the guide to the wall of the rotating chamber to revolve, and thus imparts a twist to the material between its point of engagement with the rotating chamher and its point of delivery from the drawing-rolls, which are continually feeding the roving forward. The rapidity of rotation of the chamber is such that the centrifugal force on the short length of yarn extending laterally from the guide to the interior of the chamber is sufiicient to pull the yarn or twisted material forward through the guide, and the spun yarn is thus laid upon the inner wall of the rotating chamber in proportion as it is delivered by thedrawing-rolls, and by giving the guide-eye the proper traverse the yarn is thus coiled or laid upon different parts of the inner surface of the chamberwith the distribution desired, thus building a definitelycoiled mass of spun yarn inside of the hollow spinning-chamber.

It has been proposed to spin yarn by means of a rotating hollow chamber or cup upon the interior of which the spun material would accumulate in the form of a hollow coil; but this plan has proved impracticable on account of mechanical difficulties encountered in the production of an apparatus to operate in such manner and because the material thus accumulated in the form of a hollow coil could not be removed from the spinning appliances in condition to be subsequently utilized in weaving or for other purposes without involving greater cost in time and labor than would compensate for the advantage which pertained to this method of spinning as compared with the methods now generally practiced in which the material is wound continuously or intermittingly in the spinning operation upon a bobbin or cop in proper condition for subsequent handling.

When a sufficient mass of yarn has been spun and coiled upon the inner surface of the spinning-chamber, it must be removed therefrom; and the present invention consists partly in the combination with the above-described twisting and collecting appliances of eflicient means for thus removing the spun yarn from the hollow cylinder without interrupting its rotary movement, which will be described in connection with drawings, which illustrate a convenient and efficient embodiment of the invention.

Figure 1 is a front elevation of the lefthand end of a spinning-frame provided with appliances embodying this invention for spinning yarn and winding the spun yarn upon bobbins and removing the filled bobbins from the spinning appliances, a portion of the framework being broken away and some parts being shown in section to better show certain parts of the actuating mechanism and a portion of the roving-bobbins at the upper part of the frame being removed. Fig. 2 is a similar front elevation of the right-hand end of the spinning-frame, portions of the framework being broken away to better show the traverse mechanism which governs the distribu' tion of the spun material in the spinningchambers and when subsequently wound upon the bobbins. Fig. 3 is an elevation of the left-hand end of the spinning-frame. Fig. 1 is a transverse vertical section on a line X", Fig. 2, with the spinning-chamber and the parts directly associated therewith at the front of the machine shown in elevation and the corresponding parts at the rear of the machine shown in vertical longitudinal section. Fig. 5 is a transverse vertical section on line X, Fig. 2, illustrating a portion of the traverse mechanism.
